40、 I have learned something about smoking in our country and Id like to answer all your questions. As far as I know, more and more people have realized smoking does great harm to health. As a result, they have made up their minds to give up smoking. It is a pity that we dont have a law banning smoking in public places, but there are signs reminding people to limit smoking in public places. Im sure our government will take measures to help people to do so. Thats all I know about smoking in our country. Hoping that it will be helpful to you. Keep in touch and best wishes! Yours，Zhou Kai
